Reboot-Oriented IoT: Life Cycle Management in Trusted Execution Environment for Disposable IoT devices
Kuniyasu Suzaki, Akira Tsukamoto, Andy Green, Mohammad Mannan · Annual Computer Security Applications Conference · 2020
Many IoT devices are geographically distributed without human administrators, which are maintained by a remote server to enforce security updates, ideally through machine-to-machine (M2M) management. However, malware often terminates the remote control mechanism immediately after compromise and hijacks the device completely. The compromised device has no way to recover and becomes part of a botnet. Even if the IoT device remains uncompromised, it is required to update due to recall or other reasons. In addition, the device is desired to be automatically disposable after the expiration of its service, software, or device hardware to prevent being cyber debris.
